T at whom it may concern.-

Be it known that I, EMIL HELBING, a subject of the German Emperor, and aresident of Wandsbeck-Hamburg,Germany,haveinvented a certain new anduseful Process of Manufacture of Peat Briquets, of which the followingis a specification.

This invention has reference to the manufacture of peat briquets orblocks intended to serve as fuel and in which peat is the chiefconstituent; and the objects of my invention are to enable peat briquetsto be made more cheaply than hitherto, which briquets, besides beingreadily combustible, will continue to glow and give 01f greatheat untilthe carbon contained in them has been practically completely consumed,and to obviate a defect, hereinafter referred to, appertaining to allprocess of manufacture ofpeat briquets heretofore.

In making peat briquets the peat sods have hitherto been first dried,either by exposure to the air or by heating them or even v carbonizingthem, and the dried or carbonized peat has then had mixed orincorporated with it some inflammable material and also some bindingmaterial, the mass being then pressed in suitable molds. This processhas the defect that the drying or the carbonizing oflthe peat sodscauses a deterioration or even the abstraction or destruction of theinflammable' and binding properties possessed by the natural peat, whichdefect is obviated by my invention.

In my improved process of manufacture of peat briquets I take the peatin its natural and more or less wet state and incorporate with it milkof lime and oxid of manganese, which latter may, if desired, be replacedby any other oxygen-generating material, and I press the resultant massin molds, so as to form briquets, which I then dry, when they will beready to be used as fuel. If the peat be of poor quality, lacking incarbon, the

composition would be improved in its heatgiving quality by adding orincorporating with it fats, oils, waste containing such, resin,

bitumen, tar products, pitch, coal-dust, or
